ADJUSTABLEHOOD FOR VAPOR-STOVES.

SPECIFICATION forming part of Letters Patent No. 641,247, dated January 9, 1900.

Application filed June 13,1899. Serial No. 720,420. (No model.)

To rtZZ whom it may concern:

Be it known that I, SAMUEL A. WILSON, a citizen of the United States, residing at Ocheyedan, county of Osceola, State of Iowa, have invented a new and useful Adjustable Hood for Vapor-Stoves,of which the following is a specification.

The object of this invention is to provide a hood specially designed for use in connection with vapor-burning stoves, which hood may be supported immediately over a stove, to thereby receive all of the gas and odor'arising from the stove when the generation of gas is started, and which may be readily raised so that access maybe had to the top of the stove, and, further, the said hood may be readily and quickly raised or lowered and temporarily secured in either position, so that whenever the vapor or odor arising from the stove becomes objectionable the said hood may be drawn down close to the stove to thereby conduct the vapor and odor to the outside of the building, and it may also be raised so as not to interfere with the operations upon the stove.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device, as hereinafter more .fully set forth, pointed outin my claim and illustrated in the accompanying drawing, in which the figure shows a vertical section of the complete device.

Referring to the accompanying drawing, I have used the reference-numeral 10 to indicate the hood, which is preferably made 'of sheet metal and is provided with a central opening 11 at its top and a handle 12 on its front edge fixed to the top of the hood, and surrounding the opening 11 is a pipe-section 13 to project straight upwardly, and on the front and back surfaces of this pipe 13 are the guiding-loops 14.

The reference-numeral 15 is used to indicate a Stovepipe of the ordinary dimensions having a part projecting straight downwardly, which part is designed to telescope into the pipe 13. This pipe is preferably supported by means of a rigid brace 16, formed in an elevated support, and fixed to the front edge of the pipe 15 is a rod 17, to project first forwardly and then downwardly, and near the upper end of said rod 17 is a bend 18. This rod passes through the loop 14 and is made of resilient metal, so that when the hood is raised to its upper limit the loop 14 will engage the bend 18, and thereby support the hood in its elevated position. At the rear of the pipe 15 isa second rod 19, which passes through the loop 14 at the rear to serve as a guide.

In practical use and assuming that the hood is in its lowered position, it may be raised by grasping the handle 12 and pulling it upwardly until the loop 14 enters the bend 18,

whereupon the rod 17 will spring outwardly and support the hood in its elevated position. To prevent the possibility of the pipes binding when the handle 12 is grasped to elevate the hood, at the rear of the pipe 13 I have formed a long vertical groove 21, by bending the metal outwardly, and in this groove a number of balls 22 are placed, and in the front of the pipe 13 a short groove 20 is provided, by bending the metal outwardly, and said groove is shallow at its upper end and deep at its lower end. Into this forward groove a single bearing-ball 22 is placed by forcing it downwardly through the space between the shallow groove and the inner pipe, and obviously when it is once down it will drop into the larger end or pocket at the bottom of the groove, where it may freely rotate without danger of working upwardly and dropping out when the hood is raised. In the rear groove this is unnecessary on account of its greater depth. This construction is very advantageous for the reason that the hood is always grasped at the front-end, and by providing a number of balls at the rear a long bearing-surface is provided that serves to prevent binding when the hood is raised. This is not necessary at the front, but it is advantageous to throw all of the friction upon a single ball, thus holding the pipes away from each other to such a degree at least as to greatly lessen the friction and to make the movement of the pipes with relation to each other easy of accomplishment.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is-

An adjustable hood for vapor-stoves, comprising in combination a hood proper 10, a handle 12 at its front edge, a pipe-section 13 fixed to the top of the hood, apipe-section 15 telescopically'connected with the pipe 13 and having a long vertical groove in its rear surbearing-ball in the front groove, substanface andashortvertical grooveinitsfront snrtially as and for the purposes stated. face at, its top said front groove being deeper I SAMUEL A.
